Connectors for electrical and electronic equipment - Tests and measurements - Part 99-002: Endurance test schedules - Test 99b: Test schedule for unmating under electrical load

IEC 60512-99-002:2022 est disponible sous forme de IEC 60512-99-002:2022 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.  L’IEC 60512 est utilisée pour évaluer des connecteurs relevant du domaine d’application du SC 48B, qui sont utilisés dans les câblages de communication à paires torsadées permettant une alimentation à distance, tels que les câbles à paires symétriques conformes à la classe D de l’ISO/IEC 11801‑1 ou à une classe supérieure, à l’appui de la norme IEEE 802.3btTM (Power over Ethernet (alimentation électrique par câble Ethernet), prenant en charge jusqu’à 90 W provenant de l’équipement de source d’alimentation). L’objet du présent document est de détailler un programme d’essai permettant de déterminer l’aptitude des jeux de connecteurs à supporter au moins 100 manœuvres mécaniques avec charge électrique lorsqu’un courant électrique traverse les connecteurs conformément à l’IEC 60512‑9‑3 pendant la séparation (désaccouplement). Cette deuxième édition annule et remplace la première édition publiée en 2019. Cette édition constitue une révision technique. Cette édition comprend les modifications techniques importantes suivantes par rapport à l’édition précédente : Le groupe d’essai UEL a été révisé en ce qui concerne l’ordre des phases de test, les sévérités des tests et les exigences.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
This redline version of the official IEC Standard allows the user to identify the changes made to
the previous edition IEC 60512-99-002:2019. A vertical bar appears in the margin wherever a
change has been made. Additions are in green text, deletions are in strikethrough red text.

IEC 60512-99-002 has been prepared by subcommittee 48B: Electrical connectors, of IEC
technical committee 48: Electrical connectors and mechanical structures for electrical and
electronic equipment. It is an International Standard.
This second edition cancels and replaces the first edition published in 2019. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Test group UEL has been revised with respect to the order of the test phases, the test
severities and the requirements.
The text of this International Standard is based on the following documents:
Draft Report on voting
48B/2922/FDIS 48B/2938/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/standardsdev/publications.
A list of all parts in the IEC 60512 series, published under the general title Connectors for
electrical and electronic equipment – Tests and measurements, can be found on the IEC
website.
Future standards in this series will carry the new general title as cited above. Titles of existing
standards in this series will be updated at the time of the next edition.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates that it
contains colours which are considered to be useful for the correct understanding of its
contents. Users should therefore print this document using a colour printer.

CONNECTORS FOR ELECTRICAL AND ELECTRONIC EQUIPMENT –
TESTS AND MEASUREMENTS –
Part 99-002: Endurance test schedules –
Test 99b: Test schedule for unmating under electrical load

1 Scope
This part of IEC 60512 is used for testing the assessment of connectors within the scope of
SC 48B that are used in twisted pair communication cabling with remote power, such as
ISO/IEC 11801-1 Class D, or better, balanced cabling in support of IEEE Std 802.3bt™, (PoE
TM
Plus – Power over Ethernet Plus) IEEE 802.3bt (Power over Ethernet, supporting up to 90 W
from the power sourcing equipment).
The object of this document is to detail a test schedule to determine the ability of pairs sets of
connectors to withstand a sequence of tests with a total of 100 engagements and separations.
The electrical current is passed through the connectors during the separation (unmating) step
only, in accordance with IEC 60512-9-3 minimum of 100 mechanical operations with electrical
load, where an electrical current is being passed through the connectors in accordance with
IEC 60512-9-3 during the separation (unmating) step.
